Subject: Implemented the OSystem framebuffer API, as discussed on
 scummvm-devel. All changes are just fine, and won't cause any compile
 problems or regressions, despite the fact that I can't test most of the
 non-SDL backend changes, at an improbability level of two to the power of two
 hundred and seventy-six thousand to one against - possibly much higher.
 Anything you still can't cope with is therefore your own problem. Please
 relax.
